The radius of the circular path r = 2m

Angular velocity \(\omega\) = 4 rad/s

Angular acceleration α is rate of change of angular velocity 

α = \(\frac{\omega}{t}\)

Here in the question, the angular velocity is given as constant.

Therefore,the angular velocity is not changing with time

Thus,angular acceleration α = 0
